JEWELERS BRAZING-LAM P..

SPECIFICATION forming part of Letters Patent No. 656,654, dated August 28, 1900.

Application iiled October 6,1899. Serial No. 732,666. (No model.)

To all whom t may concern,.-

Beit known that I, HERMOND L. MCCOR- MACK, a citizen of the United States, residing at Menard, in the county of Randolph and State of Illinois, have invented a new and useful Improvement in Jewelers Brazing- Lamps, of which the following is a specification.

This invention is an improved construction of brazinglamp particularly adapted for jewelers use, the object being to provide an exceedingly cheap, simple, and efficient de- .vice by means of which a jet-flame of intense heat can be secured; and with these objects in view the invention consists in the peculiar construction of the various parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speciiication, Figure l is a side elevation of a lamp constructed in accordance with my invention. Fig. 2 is a vertical sectional view. Fig. 3 is a detail of the jet-nozzles, and Fig. 4E shows a slight modification.

In carrying out my invention I employ a suitable tank A, having an inlet-opening A at the top, which is normally closed by means of a stopper or plug which may act as a safetyvalve. The tank A is preferably constructed in spherical form and is provided with an exterior circumferential rib or iiange adapted to rest upon a suitable support B. The tank or receptacle A is intended to receive alcohol, and the pipe C is located within the said tank or receptacle, the upper end thereof extending nearly to the top of the same, while the lower end is projected out of the said tank in a horizontal direction at the bottom of the said tank, the outer end of said pipe being provided with a jet-nozzle C', said jetnozzle being removable, so that diiferent sizes or styles of jets can be employed, according to the character of the flame desired. The support B is substantially semicircular and has its ends bent down at right angles thereto to form legs Bi, and its central portion is secured to a rod or bar B3, which also forms a leg as well as a handle by which it may be carried. The upper end of the rod is preferably provided with an opening, by means of which it may be suspended from the wall. Secured to said legsmear the bottom,is a suitable base-plate B A spirit-lamp of any deL sired construction is adapted to rest upon the base-plate B', with its burner directlyin line with the end of the pipe and its jet-nozzle. In operation the spirit-lamp is lighted, thereby vaporizing the alcohol within the tank, which vapor passes through the pipe O out through the jet-nozzle and commingles with the flame from the spirit-lamp, thereby producing a vapor jet-iiame equal in intensity, if not greater, than the heat of a blowpipeflame. By means of this construction it will be seen that I provide a brazing-lamp consisting of very few parts and bymeans of which a fine jet-flame can be obtained.

In Fig. 4t I have shown a slight modification in which the tank and spirit-lamp are supported upon the tripod by means of chains E, and the spirit-lamp is preferably constructed with two burners, one adapted to rest directly beneath the jet-nozzle and the other some distance in advance, so that the vapor-jet will commingle with the llame in advance of the nozzle.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In abrazing-lamp, the combination,with a stand provided with three legs, the upper ends of two of which are provided with a substantially-semicircular support, and the other leg secured to the intermediate portion of said support and extended above the same, of a receptacle upon the support the bottom of which is provided with an outlet, and means for supporting a lamp below the receptacle in position to cause its flame to impinge upon said outlet, substantially as described..

2. In a brazing-lamp, the combination with a rear rod, the upper end of which is provided with an opening, of a support secured thereto, said support being semicircular and having its ends bent at an angle to form-legs, and means for supporting a receptacle and a lamp thereon.

B. In a brazing-lamp, the combnation,with a rear rod, the upper end of which is provided with an opening, of a support secured a nozzle, and a. lamp under the nozzle, subto the intermediate portion of the rod, said stantially as described. support being semioircular and having its ends bent at an angle to form legs, a. base- HERMOND L' MCCORMACK' 5 plate secured to said legs and to the rear rod Witnesses:
